The present disclosure provides a sealing member that includes insertion holes into which connector terminals are inserted, wherein the sealing member exhibits a high water sealability and damage caused when the connector terminal is inserted into the insertion hole is suppressed. The present disclosure also provides a waterproof connector that includes the sealing member. A sealing member 10 includes: a silicone rubber that is formed as a plate-like member; and insertion holes 11 that are formed in a plate surface of the plate-like member and into which connector terminals 20 can be inserted. The silicone rubber has an unnotched Charpy impact strength at −60° C. of 11.5 kJ/mm.sup.2 or more. A waterproof connector 1 includes the sealing member 10 and the connector terminals 20. The connector terminals 20 are inserted into the insertion holes 11 of the sealing member 10.

Provided is a connector in which first and second connector members are fitted with each other. The first connector member includes a first housing formed with a protrusion. The second connector member includes a second housing; hood member; elastic member; and locking mechanism. The hood member is to cover and to be mounted with the second housing. The elastic member is to be provided between the hood member and second housing. The locking mechanism is to lock the protrusion. The locking mechanism is operated so that the protrusion is drawn in a fitting direction. After the movement of the first and second connector members in the fitting direction is restrained, the locking mechanism is operated so that the hood member is moved while compressing the elastic member, which fix the locking mechanism with the elastic member being compressed.

A seal (30) to be mounted into a rear part of a housing 20 and is formed with seal holes (32) configured to allow wires (26) connected to rear parts of terminal fittings (24) to pass therethrough in a liquid-tight manner. The seal (30) includes a body (31) constituting rear areas (32R) of the seal holes (32) and having an outer peripheral lip (37) formed on an outer periphery. An area between inner peripheries of the seal holes (32) and the outer peripheral lip (37) defines a solid resilient portion (39). Following portions (40) project forwardly of the outer peripheral lip (37) from a front surface of the body (31). The following portions (40) constitute front areas (32F) of the seal holes (32) and are resiliently deformable in directions intersecting a penetrating direction of the seal holes (32).

A three-dimensional (3D) printed electrical connector includes an insert component, at least a first sealing member, and a shell. The insert component includes a body adapted for 3D printing. The body has first and second ends and includes a cavity penetrating the body along a longitudinal axis of the body. The first sealing member is associated with the insert component and is adapted for 3D printing. The shell at least partially encloses the insert component.

Disclosed is a shield connector for supporting cables such that terminals of the cables are directly connected to a terminal coupling portion inside a unit, the shield connector including: a fixing plate which includes fixing part-cable through-holes, through which the cables pass, and a holding fastening portion; and a sub assembly which includes movable part-cable through-holes, through which the cables pass, and has one surface supported by the fixing plate. The sub assembly includes: a shield plate which is in contact with shield portions of each of the cables and has the outer circumference in contact with a shield part of the unit; and a shield plate-fixing plate having one surface that fixes the shield plate. Therefore, the shield connector makes it possible to directly install the cable in the unit without the need for the separate male and female connectors.

An electrical connector is provided that includes a plurality of electric cables. A first adapter is configured to receive the electrical cables. The first adapter protects the electrical cables and allows for an electrical connection between the electrical cables and a plurality of electrical pins. A second adapter is coupled to the first adapter. The second adapter allows for an electrical connection between the electrical pins and a plurality of electrical terminals. A cable kit is provided that is at least partially housed within the second adapter. The cable kit has a plurality of projections extending therefrom. An insulator body is coupled to the second adapter. The insulator body includes a plurality of openings. Each of the openings has a tapered end portion configured to receive a corresponding one of the plurality of projections of the cable kit to form a mechanical seal with the cable kit.

An electrical connector includes: a metallic cover; an insulative frame molded inside the metallic cover; a metal injection molded (MIM) support and a contact module received by the MIM support, the contact module having a rear base, a front tongue, and an upper and a lower rows of contacts extending through the base and exposing to two opposite faces of the tongue, the MIM support having a pair of side arms flanking the two rows of contacts; and an insulator molded outside the MIM support and the contact module and secured to the insulative frame.

A connector waterproofing structure watertightly seals a gap between openings of cavities of a pair of housings which accommodate terminals. In the structure, the pair of housings includes annular members formed at each of ends of the openings. The annular members are made of resin, protrude and surround the openings, either one of the annular members is formed into such a shape to be pressed to an inner peripheral surface or an outer peripheral surface of the opposite annular member, when the pair of housings are fitted together, and the inner peripheral surface or the outer peripheral surface are obliquely formed so that the wall thickness of the opposite annular member is gradually increased from the distal end toward the back.

The seal spring of the present invention has a dual functionality. The seal spring provides both a sealing property and spring function in use within an electrical connector system, which is accomplished by its elastomeric qualities The seal spring is preferably comprised of Silicone, EPDM rubber or materials and compositions that provide similar performance during use, or the like. The seal spring of the present invention is not limited or defined into a spring section or a seal section by its geometry. Shown is an implementation of the seal spring within a conductive female housing and connector assembly. The seal spring compresses and provides adequate spring force against a disk ferrule assembly, pressing the disk ferrule assembly, with a wire shield, against a conductive female outer housing, providing a grounding scheme for the connector assembly. The seal spring also seals against the female outer housing and a wire.
